[Carnivore] liked the sound of his Beats Pro headphones but hated the wires. After disassembling the headphones, he carefully rewired the speakers with smaller gauge wire, added a small Bluetooth module and battery, and sealed everything back up.

There are a few interesting bits to this build – by getting rid of all external wires, [Carnivore] was left with a few holes in the headphones. These were a perfect place to add a 3D printed mount for the power button and the Lightning adapter taken from an Apple Lightning extension connector.
